Classic Game Room presents a CGR Undertow video game collectible review of the Super Mario Bros. 3 Electric Toothbrush. Released sometime after 1990 to promote the release of Super Mario Bros. 3 for the NES, this had kids back in the day happy to brush their teeth with Nintendo Power! 4 out of 5 Nintendentists agree, this handy tool will help you fight off cavities like they were Goombas. And surprisingly enough, it still seems to work with a twenty year old battery! This review demonstrates the use of the Super Mario Bros. 3 Electric Toothbrush with commentary from CGR Undertow reviewer Kevin.
